GHD7 — Oryza sativa Japonica

Summary

OS07G0261200 (GHD7) encodes a CONSTANS-like protein with a CCT domain that localises to the nucleus and binds DNA and zinc. In rice, GHD7 is associated with flowering time, photoperiodism, and the regulation of both short-day and long-day flowering pathways, as well as vernalization response, leaf senescence, and hormone, sucrose and chlorophyll metabolism. The gene has been linked to numerous agronomic traits including heading date, grain number, grain plumpness, grain size, panicle number and length, tiller number, plant height, yield, stress responses (both abiotic and biotic), cadmium concentration, photosynthetic rate, and overall growth and development. Studies of related genes in other species connect the family to traits such as stay green, kernel number, and heat tolerance.
